    Perovskite oxide Method for fabricating the same and Anode of Solid Oxide Fuel Cell comprising the same

    본 발명의 다양한 실시예에 따른 페로브스카이트 구조 산화물은, 하기 화학식 1로 표시된다. [화학식 1] La0.8-xSrxFe0.12-yCuyTi0.88O3-δ (여기서, x는 0.2 내지 0.6이고, y는 0.01 내지 0.2이고, δ는 -0.005 내지 0.975이다.) 본 발명의 다양한 실시예에 따른 페로브스카이트 구조 산화물의 제조 방법은, 출발물질을 상기 화학식 1의 화학양론에 따라 용매와 함께 혼합하는 단계; 상기 용매를 제거하여 파우더를 수득하는 단계; 상기 파우더를 프레싱한 후 가소결하는 단계; 및 상기 소결체를 분쇄 후 최종 소결하는 단계를 포함할 수 있다.

    A perovskite-structured oxide according to various embodiments of the present invention is represented by chemical formula 1, La_(0.8-x)Sr_xFe_(0.12-y)Cu_yTi_0.88O_(3-δ), where x is 0.2 to 0.6, y is 0.01 to 0.2, and δ is -0.005 to 0.975. A method for manufacturing the perovskite-structured oxide according to various embodiments of the present invention comprises the steps of: mixing a starting material with a solvent according to the stoichiometry of the chemical formula 1; obtaining powder by removing the solvent; pre-sintering the powder after pressing the powder; and performing final sintering after crushing the sintered body. The perovskite-structured oxide may have enhanced catalytic performance.
